The European starling is considered an invasive species in Oregon. It was introduced from Europe.
They most closely resemble blackbirds, with which they often flock in fall and winter. While both have iridescent plumage, starlings can be told from blackbirds by their two-toned wing pattern - dark upperwing, pale underwing - and during the breeding season by the bright yellow bill.
Starlings adapt readily and quickly to human habitation and are highly efficient and successful breeders. However, the abundance of the bird, the rapidity with which it has spread across North America, and its propensity to cause damage to crops and native bird populations cause the starling to be disfavored by many and remind us of how much damage an introduced species can cause.
They are a common to abundant breeder in urban areas, and locally common in agricultural areas throughout the state where buildings and trees are present.
